T0 .all whom it mtg/ concern: l

Beit known that I, JOHN R. WHITTEMORE. a citizen of the United States,residing at Erie, in the county of` .Erie and State of Pennsylvania,have invented certain new and useful Improvements in CraneMechanism; andI do hereby declare the'following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to theletters of reference markedthereon, forming part `.of this speciiication.

This invention relates to improvements in crane mechanism, and has forits object a combination and arrangement of jib-cranes with a travelingcrane in such a manner that a trolley-hoist mechanism will operate onboth the jib and traveling cranes and pass from one to the other, sothat work can be transferred froml one of the jib-cranes to thetraveling crane and from the traveling crane to any one of thejib-cranes, as may be desired.

A further feature of my invention is the providing of mechanism wherebythe traveling crane can be locked on its track opposite any one of thejib-cranes and the jib-crane can be locked in line with the travelingcrane, so that the trolley-hoist mechanism willtravel from one crane tothe other.

The features of this invention are herein: after set forth anddescribed, and illustrated in the accompanying drawings, in which-Figure l is a top or plan view of a combined traveling-crane andjib-crane mechanism embodying my invention. Fig. 2 is a transverse viewin elevation of the same. Fig. 3 is a sectional view of thetraveling-crane mechanism on the line w in Fig. 2.

In the drawings, A is the track, and A the track-support, of a travelingcrane, .preferably supported by brackets B, secured to overhead beams B,as illustrated` iny Fig. 2, and preferably extending through a shop.Upon the trackAthere is mounted a traveling crane the general featuresof which-viz., the brackets O, forming the ends thereof, thetrolleywheels C', and the transverse shafts Cz-are of the usualconstruction. The brackets C,

however, extend down below the track-sup- -ports A and have securedthereto a transverse horizontal I-shaped beam D, which forms atrolley-track D for a trolley-hoist mechanism E.

In one of the brackets C there is mounted a latch c, operated by adepending cord c' and Aeling hoist mechanism E. The arms F of thejib-cranes F are on the same horizontal plane as the I-beam D of thetraveling crane, and

when any one of the jib-crane arms F' are moved so as to be at rightangles to the tracksupport A' and the traveling crane brought oppositethereto, as shown in Figs. l and 2, the jib-crane arms F and I-beam D onthe traveling crane will then coincide and form a continuous track F2 D,as shown in Fig. 2, over which a trolley-hoist E will travel. To retainthe arms Fl at right angles to the tracksupport A', as above described,I provide a latchf, mounted on the crane-arm F' and provided with anoperating-cord f. This latch f is adapted to engage a stop c on thetracksupport Al when the arm F is at right angles therewith. Y

Referring to Fig. l, I have shown two machines G and H, adapted to bereached and served by the jib-cranes F on that side of the shop and fromwhich work can be hoisted and carried by one of the jib-cranes F anddelivered to the traveling crane, so as to be deposited under thecranewayor carried by the traveling crane to another part of the shopand delivered to another of the jib-cranes on either side of the shop,and vice versa, as may be desired.

In the drawings, it will be observed, I have shown the jib-cran'es andthe traveling crane as of the ordinary conventional construction, as myinvention consists rather in the arrangement of the cranes with relationto each other and the modiiications of construction necessary to adaptthem to coperate substantially as described than to the use of anyparticular type of either jib or traveling crane, as any form of suchcranes could readily be arranged and modified in their construction soras to practically embody m'y invention.

Therefore having thus shown and described convenient mechanism embodyingmy invention, so as to enable others to utilize the same, what I claimas new, and desire to secure by Letters Patent of the United States, is-

l. The combination of a traveling crane, a

transverse horizontal trolley-track thereon, a jib-crane on one side ofthe line of travel of the traveling crane, a horizontal trolley-trackthereon on the same horizontal plane with the trolley-track on thetraveling crane, means for locking the jib-crane trolley-track at rightangles to the line of travel of the traveling crane, means for lockingthe traveling crane so that the trolley-track thereon will coincide withthe trolley-track on the jib-crane when itis at right angles to the lineof travel of the traveling crane.l and a trolley-hoist adapted tooperate over both of said trolley-tracks when they coincide as aforesaidand pass from one to the other, substantially as set forth.

2. The combination of a traveling crane, tracks therefor supported fromabove, a transverse horizontal track on said crane below thetrack-support thereof, a series of jib-cranes on one or both sides ofthe traveling-crane supports, horizontal trolley-tracks on saidjibcranes on the saine horizontal plane with the trolley-track on thetraveling crane, means for locking each of said jib-cranes at rightangles to the track-support of the traveling crane, latch mechanism forlocking the travcling crane in line with each of said jib-cranes when atright angles with the track-support so that the trolley-track on thetraveling crane will coincide with the trolley-track on the jib-craneopposite thereto, and a trolley-hoist adapted to travel over thetrolley-track on the traveling crane and the trolley-track on thejib-crane coinciding therewith, and from one to the other, substantiallyas set forth.

In testimony whereofl I affix my signature in presence of twowitnesses.`
